vivid-hd-20.jpgNew from Crystal Vision is ViViD HD-20 – a variable video delay line designed for engineers who need to match any long delays in their system. Not only does this unusual product provide an exceptionally long delay with up to 21 seconds in HD and 119 seconds in SD, it also saves space by allowing 12 video delay modules to fit in just 2U of rack space.

ViViD HD-20 is ideal for use as part of a profanity delay system, or to match MPEG encoders and decoders, MPEG-compressed HD radio links or virtual studio graphics that require more than half a second of HD delay. The output timing is based on the video input and is adjustable in seconds, frames, lines and pixels for true flexibility. ViViD HD-20 has a minimum delay of 12us in High Definition and 46us in Standard Definition.

ViViD HD-20 delays not just the active picture but the entire video stream with embedded audio and ancillary data staying with the associated video, allowing it to be used without restrictions in embedded areas. 16 presets can be assigned and recalled through GPIs, therefore saving the broadcast engineer time by allowing different delay values to be recalled automatically by the studio control system.

Explained Crystal Vision’s Managing Director, Philip Scofield: “ViViD HD-20 is the most complete solution to video delay. It has a huge delay, a small physical size making it so different from the space-consuming boxes offered elsewhere, and the ability to delay any embedded data.”

ViViD HD-20 is a 100mm x 266mm module which fits in Crystal Vision’s standard rack frames alongside any of the interface, keying or picture storage products (including the company’s chroma keyers), allowing 24 video delays in 4U, 12 in 2U, six in 1U or two in a desk top box. It uses the RM44 frame rear module which gives three HD or SD outputs – potentially saving the engineer a distribution amplifier in his system design. The programme output is also protected with relay bypass protection of the input in the event of power failure or board malfunction or removal. Easy to set up and use, the flexible control options include board edge switches, an active front panel on the frame, a remote control panel or the Statesman PC software.

Shipping now, ViViD HD-20 is part of the Picturestore product range – Crystal Vision’s sophisticated new area of speciality based on solid-state fast reading and writing picture storage. Other products in the Picturestore range are the MultiLogo logo keyer, Clip N Key clip and sting store and Playback instant replay device.

Based at Whittlesford near Cambridge in the UK, Crystal Vision provides digital keyers, picture storage modules and a full range of interface equipment including converters, decoders, encoders, distribution amplifiers and audio embedders to the professional broadcasting industry worldwide.
